It was supposed to be a tough match because Manchester City and Manchester United are big clubs, and it is also a derby match that both clubs want to win to prove they are the kings of Manchester. When it comes to the Manchester derby, Manchester City always wins easily against Manchester United. Haaland will perform better than Hojlund because Manchester City will dominate the match and create more chances, while Manchester United will play defensive football and depend on a counterattack to score goals.
At least Manchester United should prevent to be humiliated
For Manchester United to do that, they need to play defensive football, which will make Manchester City struggle to score goals. But if Manchester United wants to play attacking football against Manchester City, I think Manchester City might score Manchester United from three goals up.
